Flex board is a printed circuit made of flex insulating substrate. Flex circuits provide excellent electrical performance, which can meet the design needs of smaller and higher-density installations, and also help reduce assembly processes and enhance reliability.
Flex circuit boards are the only solution to meet the miniaturization and mobility requirements of electronic products. It can be freely bent, wound, and folded, and can withstand millions of dynamic bends without damaging the wires. It can be arranged according to spatial layout requirements, and can move and expand freely in three-dimensional space, achieving the integration of component assembly and wire connection; Flex circuit boards can greatly reduce the volume and weight of electronic products, making them suitable for the development of electronic products towards high density, miniaturization, and high reliability.
The characteristics of flex boards
Flex circuit board, also known as flex circuit board or flexible circuit board, abbreviated as flex board or FPC. It is a circuit board mainly composed of CU, acrylic, epoxy resin thermosetting adhesive, and PI. It has the advantages of high wiring density, lightweight, thin thickness, limited wiring space, and high flexibility. It is widely used in production and daily life, and the market is still expanding.
1. Reduce the volume of application products, save space, significantly reduce weight, increase effectiveness, and reduce costs.
2. Highly flexible, capable of three-dimensional wiring and changing shape according to space limitations.
3. Foldable without affecting signal transmission, or anti-static interference.
4. High and low-temperature resistance, and flame resistance.
5. Stable chemical changes, high stability and reliability.
6. Providing more solutions for related products can reduce assembly time and errors, and improve the service life of related products.
The difference between flex board and rigid board
PCB flex board and rigid board are two common types of boards in the electronics industry, playing different roles in board design and manufacturing processes. Although their names are similar, their design and manufacturing methods are different.
1. Materials
Flex board is a type of flex circuit board made of flexible materials such as polyester film, polytetrafluoroethylene film, etc.
Rigid board is a circuit board made of hard materials such as glass fiber-reinforced resin.
2. Application scope
Due to its flexibility, flex boards are particularly suitable for applications that require bending and bending, such as in wearable devices, mobile phones, car interiors, car bodies, and certain high-precision electronic devices.
Rigid boards are commonly used in applications that require greater strength and robustness, such as computer internal structures, mechanical and industrial products, and complex circuit manufacturing.
3. Electrical performance
Although flex boards can still function under bending or twisting, they may have limitations in electrical performance, such as lower signal transmission speed and impedance control stability compared to hard boards.
The electrical performance of rigid boards is more stable and reliable, especially in high-density wiring applications.
Compared with traditional rigid boards, flex boards have high flexibility and flexibility, adapting to various complex shapes and spatial layouts, making circuit board design more flexible and diverse. It has the advantages of small size and light weight, greatly reducing the size and weight of the device, and making it more convenient to carry electronic devices.
